My wife, daughter and I stayed here for a week in February. The place is accurately described as advertised. Finding the condo for the first time was a challenge as there is a lot of construction and many different exits from Shibuya train station that lead us in the wrong direction.
The first two days of our trip were very cold. And the heater in the condo was inadequate due of the lack of insulation from the sliding glass doors. The heater ran contently an could not reach the maximum setting of 30 degrees Celsius.
Also, the bandwidth on the WiFi is very slow. Any more than two connections will bring the system to a halt.
But if you are looking for a less expensive place in a good location then this may fit your needs.
